FIG. 1 is a flowchart of a control method according to an example of the present disclosure. As shown in FIG. 1, the method may be applied to an electronic device having a camera, and includes the following operations.

In operation 101, a preview image is displayed.

In operation 102, a user input acting on the preview image is received. The user input is used for adjustment of a display position of a target object in the preview image from a first position to a second position.

In operation 103, in response to the user input, a shooting angle of the camera is adjusted according to the adjustment of the display position.

Herein, the electronic device includes a mobile terminal and a fixed terminal. The mobile terminal includes a mobile phone, a notebook computer, a tablet computer, a wearable electronic device and the like, and the fixed terminal includes a personal computer, a television and the like. In the examples of the present disclosure, the electronic device has a camera. During the use of the electronic device, the camera may be started based on a camera application installed on the electronic device. After the camera is started successfully, the preview image may be displayed on a display screen of the electronic device.

In some examples, the preview image may include at least one shot object, and FIG. 2 is a first schematic diagram of a display interface according to an example of the present disclosure. As shown in FIG. 2, the preview image is displayed on the display interface on the display screen of the electronic device, and the preview image includes a first shot object 201 and a second shot object 202. During the implementation of the examples, the user input may be received based on any shot object included in the preview image. For example, the user input may be received based on the first shot object or the second shot object.

Herein, the first position may be a current position of the target object in the preview image, and the second position may be a target position where the target object is to be moved.

In the implementation of the example of the present disclosure, the user may observe the position of each shot object based on the preview image displayed on the display screen of the electronic device. If the position of each shot object is not the one desired by the user, the user input may be received based on the display screen, and the shooting angle of the camera may be adjusted based on the user input to adjust the display position of each shot object. In this way, the position of each shot object in the preview image can be observed in real time during the adjustment. When the shot object is not in the desired position, the adjustment can be performed in real time. As a result, the operations are simple and intuitive, thus the user's experience of using the electronic device can be improved.

In some examples, the method may further include the following operation.

A shot object of the preview image on which a selection operation is acted is detected, and the shot object is determined as the target object.

FIG. 3 is a second schematic diagram of a display interface according to an example of the present disclosure. As shown in FIG. 3, the preview image includes a first shot object 201 and a second shot object 201. In the implementation of the example, a selection operation for each shot object may be detected, and a shot object on which the selection operation is acted is determined as the target object. For example, if the selection operation acted on the first shot object is detected, the first shot object may be determined as the target object. Herein, the selection operation may be a click operation, a long press operation, or the like, and the click operation may be a double-click operation.

Taking the selection operation being a long press operation as an example, after the long press operation acted on the first shot object is detected, the first shot object may be determined as the target object. In the implementation of the example, the display position of the target object may be adjusted according to the user input acted on the target object, so as to adjust the shooting angle of the camera according to the adjustment of the display position. For example, if a slide operation on the target object is detected, a deflection direction and a deflection angle of the shooting angle of the camera can be determined based on a sliding direction and a sliding trajectory of the slide operation, and the shooting angle of the camera is thus adjusted based on the deflection direction and the deflection angle.

In some examples, shooting angle of the camera may be adjusted by controlling the rotation of the camera. For example, the camera may be mounted on a pan-tilt-zoom structure (which is provided on the electronic device), the rotation of the pan-tilt-zoom structure is controlled to drive the rotation of the camera. In other examples, when the camera assembly includes a light deflection component, the shooting angle of the camera may also be adjusted by controlling the rotation of the light deflection component. Herein, the light deflection component may include a prism, such as a triangular prism.

In the example of the present disclosure, adjustment of the shooting angle of the camera can be realized based on the user input received from the target object selected from the preview image, the convenience of the camera control can be improved, and the current position of each shot object can be directly observed based on the preview image, thereby being more intuitive.

In some examples, the user input may include a touch input. The operation of adjusting the shooting angle of the camera according to the adjustment of the display position in response to the user input may include: the display position of the target object is adjusted according to a touch gesture of the touch input, the deflection direction and/or the deflection angle of the shooting angle of the camera are determined according to the adjustment of the display position, and the shooting angle of the camera is adjusted according to the deflection direction and/or the deflection angle.

Herein, the user input applied to the target object may be the touch input. When the user input is the touch input, the deflection direction and/or the deflection angle of the shooting angle of the camera may be determined according to the touch gesture of the touch input, and the shooting angle of the camera may be adjusted according to the deflection direction and/or the deflection angle. For example, if the touch gesture of the touch input is a gesture for rotating the target object, the deflection direction of the shooting angle of the camera can be determined according to the rotation direction of the target object, and the shooting angle of the camera can be adjusted according to the deflection direction.

In the example of the present disclosure, the deflection direction and/or the deflection angle of the shooting angle of the camera can be determined according to the touch gesture of the touch input, so that the user can adjust the target object to the desired position and/or the desired angle according to his/her own requirements.

In some examples, the operation of receiving the user input acting on the preview image may include: a click input at the second position in the preview image is received. The operation of adjusting shooting angle of the camera according to the adjustment of the display position may include: a first deflection direction and a first deflection angle of the shooting angle of the camera are determined according to a relative position between the first position and the second position, and the shooting angle of the camera is adjusted according to the first deflection direction and the first deflection angle.

Herein, the second position is different from the first position. In the example of the disclosure, when the click input at the second position in the preview image is detected, the relative position between the first position and the second position may be determined to determine the first deflection direction and the first deflection angle of the shooting angle of the camera, and the shooting angle of the camera is adjusted according to the first deflection direction and the first deflection angle. In some examples, the relative position includes a relative distance and a relative direction. The relative distance may be a distance between the first position and the second position in the preview image, and the relative direction may be a linear direction from the first position to the second position. The click input may include a double-click input, a single-click input, or a long press input.

In the example of the present disclosure, the shooting angle of the camera can be adjusted based on the click input and the relative position between the first position and the second position, so that the convenience of adjusting the camera can be improved.

In some examples, the operation of receiving the user input acting on the preview image may include: a movement input that moves the target object from the first position to the second position is received. The operation of adjusting the shooting angle of the camera according to the adjustment of the display position may include: a second deflection direction of the shooting angle of the camera is determined according to the movement direction of the movement input, a second deflection angle of the shooting angle of the camera is determined according to a moving trajectory of the movement input, and the shooting angle of the camera is adjusted according to the second deflection direction and the second deflection angle.

Taking the user input being the movement input as an example, when the movement input is detected, it is represented that the user needs to move the position of the target object in the preview image. For example, the target object may be moved to the right side of the preview image, or the target object may be moved to the left side of the preview image, or the like.

In the example of the present disclosure, the movement input for the target object can be detected. When the movement input is detected, the second deflection direction of the shooting angle of the camera can be determined according to the movement direction of the movement input, the second deflection angle of the shooting angle of the camera can be determined according to the moving trajectory of the movement input, and the shooting angle of the camera can be adjusted according to the second deflection direction and the second deflection angle. In the example of the disclosure, the shooting angle of the camera can be adjusted based on the movement direction and the moving trajectory of the movement input, and the shooting angle of the camera can be adjusted in real time when the moving trajectory changes. Therefore, the convenience of adjusting the shooting angle of the camera is improved.

In some examples, the operation of receiving the user input acting on the preview image may include: a press input acting on the target object is received. The operation of adjusting the shooting angle of the camera according to the adjustment of the display position may include: an adjustment distance of the display position of the target object is determined based on preset correspondences between press force values and moving distances and a press force value of the press input, a third deflection angle of the shooting angle of the camera is determined according to the adjustment distance, a third deflection direction of the shooting angle of the camera is determined according to a press direction of the press input, and the shooting angle of the camera is adjusted according to the third deflection direction and the third deflection angle.

Herein, when the press input acting on the target object is detected, the press force value of the press input and the press direction of the press input can be determined. In this way, the adjustment distance of the display position of the target object can be determined based on the preset correspondences between the press force values and the moving distances and the determined press force value, the third deflection angle of the shooting angle of the camera can be determined according to the adjustment distance, the third deflection direction of the shooting angle of the camera can be determined according to the press direction of the press input, and the shooting angle of the camera can be adjusted according to the third deflection direction and the third deflection angle. In the example of the disclosure, the shooting angle of the camera can be adjusted based on the press input and the press direction and the press force value of the press input, so that the convenience of adjusting the shooting angle of the camera can be improved.

In some examples, before receiving the user input acting on the preview image, the method may further include: a movable range of the target object is displayed, herein the movable range is determined according to a deflection range of the shooting angle of the camera.

In some examples, the movable range of the target object may be displayed when the selection operation for the target object is detected. FIG. 4 is a third schematic diagram of a display interface according to an example of the present disclosure. As shown in FIG. 4, the preview image includes the first shot object 201 and the second shot object 202. In the implementation process, the selection operation for each shot object may be detected, and the shot object on which the selection operation is acted is determined as a target object. After the target object is determined, the movable range of the target object may be displayed on the display interface. For example, if a selection operation applied to the first shot object is detected, the first shot object may be determined as the target object.

In the example of the present disclosure, a movable range 401 of the target object may be displayed after the target object is determined. Since the movable range 401 is determined according to the deflection range of the shooting angle of the camera, the user can rationally adjust the display position of the target object according to the movable range and thus adjust the shooting angle of the camera. Therefore, it is possible to reduce the possibility of affecting the image display effect due to the limitation from the limit value of the shooting angle of the camera.

In the implementation process, the target object to be moved in the preview image may be selected based on the selection operation, and when the long press operation applied to the target object is detected, the movable range is displayed in the preview image, so that the user can directly drag the target object within the movable range and move the target object to a designated position of the preview image by adjusting the shooting angle of the camera. In other examples, after the target object is determined, the target position of the target object may also be determined based on the detected click operation, and the target object may be moved to the target position by adjustment of the shooting angle of the camera.

In some examples, the electronic device further includes a pan-tilt-zoom structure connected to the camera. The operation of adjusting the shooting angle of the camera according to the adjustment of the display position may include: the pan-tilt-zoom structure is controlled to drive the camera to rotate according to the adjustment of the display position, so as to adjust the shooting angle of the camera.

Herein, the pan-tilt-zoom structure may be provided inside the electronic device and may have one or two planes of rotation. For example, the pan-tilt-zoom structure has two planes of rotation, which may be perpendicular to each other.

The rotation angle of the pan-tilt-zoom structure in each plane of rotation may be equal to or less than 360 degrees.

In some examples, the angle of rotation of the pan-tilt-zoom structure may be set as desired. For example, the angle may be equal to 360 degrees, or 180 degrees, 90 degrees, or the like. For another example, the pan-tilt-zoom structure may be a panoramic pan-tilt-zoom. In other examples, the rotation angle of the pan-tilt-zoom structure may be less than a set angle. For example, the rotation angle of the pan-tilt-zoom structure may be less than 180 degrees. In the example of the disclosure, the rotation angle of the pan-tilt-zoom structure is set to be smaller than the set angle, so that an internal space of the electronic device can be saved compared with a case of the panoramic pan-tilt-zoom structure.

In other examples, a pan-tilt-zoom adjustment control may also be provided on the preview image. The pan-tilt-zoom adjustment control includes an icon that is displayed overlaying the preview image and is different from an object shot in the preview image.

For example, the pan-tilt-zoom adjustment control may be configured in the upper left corner of the preview image, or the pan-tilt-zoom adjustment control or the like may be configured in the upper right corner of the preview image. In other examples, multiple pan-tilt-zoom adjustment controls independent from the preview image may also be configured on the preview image, and the rotation of the pan-tilt-zoom is controlled based on the plurality of pan-tilt-zoom adjustment controls. For example, in case of multiple pan-tilt-zoom adjustment controls, the pan-tilt-zoom structure may be controlled to rotate in an XOY plane of the Cartesian coordinate based on a first pan-tilt-zoom adjustment control, the pan-tilt-zoom structure may be controlled to rotate in the YOZ plane based on a second pan-tilt-zoom adjustment control, and the pan-tilt-zoom structure may be controlled to rotate in the XOZ plane based on a third pan-tilt-zoom adjustment control.

After the pan-tilt-zoom adjustment control is configured, it may be detected whether there is an input operation acting on the pan-tilt-zoom adjustment control, and when a user input acting on the pan-tilt-zoom adjustment control is detected, the pan-tilt-zoom structure may be controlled, based on the user input, to rotate, so as to adjust the shooting angle of the camera. For example, the rotation parameter of the pan-tilt-zoom structure may be determined based on the movement parameter input by the user, and the pan-tilt-zoom structure is controlled to rotate according to the rotation parameter. The movement parameter may include direction information and displacement information input by the user, and the rotation parameter may include a rotation direction and a rotation angle of the pan-tilt-zoom structure, or the like. The user input may be a slide operation, a rotating operation, or the like.

In the example of the present disclosure, the pan-tilt-zoom structure can be rotated during the preview of the image, so that the acquisition angle of the camera is adjusted, and the preview image acquired by the camera after the acquisition angle is adjusted is displayed on the display screen of the electronic device, so that the user can determine an effect of the adjustment in time.

In the example of the present disclosure, the pan-tilt-zoom structure is provided inside the electronic device and a camera is mounted on the pan-tilt-zoom structure, then the pan-tilt-zoom adjustment control can be configured on a preview image during use of the electronic device, and rotation of the pan-tilt-zoom structure can be controlled based on a detected user input acting on the pan-tilt-zoom adjustment control. In this way, it is possible to directly control the rotation of the pan-tilt-zoom structure based on the pan-tilt-zoom adjustment control provided on the preview image, thereby adjusting the shooting angle of the camera. Since the position of each shot object in the preview image can be observed during the adjustment process, the operation is simple and intuitive, thus the user's experience of using the electronic device can be improved.

In some examples, when the user input is a movement input, it is also possible to determine the rotation direction of the pan-tilt-zoom structure according to a movement direction of the movement input, and determine the rotation angle of the pan-tilt-zoom structure according to a movement trajectory of the movement input. The operation of determining the rotation direction of the pan-tilt-zoom structure according to the movement direction of the movement input includes: the pan-tilt-zoom structure is controlled to rotate in a first plane if the movement direction of the movement input is a first movement direction, the pan-tilt-zoom structure is controlled to rotate in a second plane if the movement direction of the movement input is a second movement direction, herein the first movement direction and the second movement direction are perpendicular to each other, and the first plane and the second plane are perpendicular to each other. For example, if the first movement direction is a direction along the X axis (which faces left or right) in Cartesian coordinates, the first plane may be an XOY plane, and if the second movement direction is a direction along the Y axis (which faces upwards or downwards), the second plane may be a YOZ plane.

In the example of the present invention, the rotation direction of the pan-tilt-zoom structure can be determined according to the movement direction of the movement input, and the rotation angle of the pan-tilt-zoom structure can be determined according to the movement trajectory of the touch operation. In this way, the rotation direction and the rotation angle of the pan-tilt-zoom structure can be made to correspond to the movement input by the user, and the target object can be more accurately moved to a position desired by the user, thus the user's experience of using the electronic device can be improved.

As shown in FIG. 5, the preview image includes a first shot object 201 and a second shot object 202, and a target position (a second position) 51 of the target object may be determined within a movable range by a click operation.
